Abstract (en)

[origin: EP2090482A2] A brake fluid pressure control device for a bar handle vehicle has a front wheel brake system (F) which imparts a braking force to a front wheel (B F ) and a rear wheel brake system (R) which imparts a braking force to a rear wheel (B R ). At least one of the brake systems (F;R) has a master cylinder (M) which generates brake fluid pressure in accordance with an operation amount of a brake operation element (L), first and second wheel cylinders (W1,W2) both of which impart the brake force on one of the front and rear wheels (B F ,B R ), a first hydraulic path (A1) which communicates the master cylinder (M) with the first wheel cylinder (W1), a second hydraulic path (A2) which is branched from the first hydraulic path and connected to the second wheel cylinder (W2) and a boosting unit (S) which boosts the brake fluid pressure in the second wheel cylinder (W2) without boosting the brake fluid pressure in the first wheel cylinder (W1).
